Differential voltage to current converter having transistors of different sizes
摘要：
A voltage/current converting circuit has a differential circuit. The differential circuit has a first input terminal coupled to receive an input voltage signal, a second input terminal coupled to receive a reference voltage signal and an output terminal for outputting an electrical current in response to a comparison of the input voltage signal and the reference voltage signal. The differential circuit includes first and second transistors. The first transistor has a control terminal connected to the first input terminal and has a first dimension. The second transistor has a control terminal connected to the second input terminal and has a second dimension that is different from the first dimension.
